【Abstract】 The design of filter banks in filtered multitone modulation (FMT) which is a new multicarrier transmission technique was researched. An efficient implementation of FMT based on linear-phase FIR filter is derived by the polyphase representation of FIR. The main performance indices and design methods of prototype proposed, the performances of designed prototypes which were applied to the FMT system were studied in wireless channel.更多还原
